浅谈丘陵山区小型电动微耕机的一种设计思路

近年来随着国家对乡村振兴的重视,农业现代化发展成为一种趋势。我省丘陵、山地占全省总面积的80%以上,大型农业机械无法适合我省的实际需求,农机小型化、自动化难度大。目前针对小型农机智能化的研究非常少。文章针对电动微耕机当前市场现状进行分析,研究燃油式小型微耕机进行田间作业载荷变化规律,在此基础上对小型微耕机进行设计和调整,设计一款小型电动微耕机的测试装置,作为原型机对小型电动微耕机的田间作业载荷变化规律进行进一步的研究和分析,为将来设计适应我省丘陵山区的小型电动微耕机提供设计依据和设计思路。

CAPE型船舶在港口接卸时的若干问题

CAPE型船舶以承运矿石、煤炭等大宗散货为主,具有载货多、运货稳、费用省等特点。此类船舶易出现中垂、中拱现象,因此应制定合理的装卸计划,确定各舱货物装卸及压载水注入和排放的数量、顺序,尽量使船长各段上的浮力和重力保持一致。为提高作业效率和保障安全,应熟悉货种特性,正确选用和妥善安排机械、人力,搞好作业衔接和配合。

Legal and Economic Aspects of the Operation of Cooperatives in Polish Agriculture

The article presents the legal and economic issues connected with the formation and operation of Polish agricultural cooperatives. Additionally, it shows a brief history of cooperative development on Polish lands and statistical data on agriculture and cooperatives. Most attention is given to dairy cooperatives, cooperative groups of agricultural producers and agricultural production cooperatives. These types of cooperatives are the most popular in Polish agriculture. The fundamental law regulating the issue of cooperatives in Poland is the Cooperative Law Act of September 16, 1982. Other laws, however, also have a big influence on the business activity of agricultural cooperatives, especially the EU legal regulations. Poland membership in the European Union has created new possibilities of development for the cooperative movement.
